Prior to putting it into bridge mode, make sure your CPE is on a different subnet to the one you're using for LAN on the Honor. e.g. if you'll be using 192.168.1.0/24 for your LAN, set the CPE to 192.168.8.0/24 for example. Otherwise, you get routing issues because the CPE is still accessible on its own subnet so that you can access the management UI. Also, make sure the Honor is configured to get its WAN IP via DHCP.
